Abstract :
The thermal stability and degradation kinetic of TV set housing plastic were investigated by the means of thermo gravimetric analyzer, the experiments of separating bromine were carried with a bench-scale pyrolysis reactor. The study results showed that the weight loss curve of TV housing plastic was divided into two different stages, the thermal degradation of brominated flame retardants mainly occurred at 290°C~350°C, the HIPS resin mainly occurred at 350°C~455°C. The most of bromine can be first released from the TV housing plastic by a process of isothermal treatment (about 300°C) and vacuum (<;5kPa). The pyrolysis oil with low bromine can be prepared by a two stage pyrolysis process of waste TV plastic.
